I did some more research. It appears the model is a Rowe 4935s. I was so focused on the coin mech and the bill adaptor and finding info on the internet on those specific items, I never looked up the machine itself. Thanks for pointing that out to me.

I was able to download the manual for the machine. Obviously, it was very informative. I was able to ascertain how to read the error codes. The only error code showing is Er 80. It directs me to check the connection at P7 and P4 relating to the wiring between the OCA controller and main controller. I checked the both connectors appear to be seat properly. I am not certain how to determine which is bad. Any suggestions?

Thanks for your patience. I believe the model of the Rowe is a 4900 series. I can't find anything that specifically says "model-####". I did find the serial number and it started with 4900- five digits. Also the control assembly says 4900 control assembly (493-1500) so I am assuming that is the model.

When I left work Saturday the machine was working fine. I returned Tuesday to find a note tapes to the glass saying out of order. I then tested it by inserting a dollar and it worked fine for me. I noticed the machine was missing an item from the first slot and the machine was slanted from its normal resting spot. I assume someone rocked the machine again. I later confirmed that it was. The guy said it took his money and registeredthe money but the item got stuck and didn't drop. He shook the machone to get it to drop along with a freebie. I assume after that is when it stopped registering money.

As I mentioned earlier, when I arrived and saw the note I didn't do anything to the machine prior to putting a dollar bill in and it worked. It has continued to work since Tuesday.

Hopefully that is the correct model number. Thanks again in advance.

What model of Rowe? Is there an error code on the machine? Can you be positive the prices had not changed before you pushed reset? Do you know how to read the error codes? I'm going out on a limb and say I think the control board battery is bad that is the only reason without major issues for the prices to change. If pricing fails it defaults to zero and the mech will not accept coins also battery failure will cause control board issues. But it should come up in an error code. Just a thought.

The machine is a Rowe International and I am certain that there are no coins lodged anywhere. I don't think I included the bill adaptor type. It is a MEI model VN2501 U3.

Thanks again.
